A detailed tire rolling model (185/75R14) using the implicit to explicit FEA solving strategy is constructed. High-quality hexahedral meshes of tread blocks are obtained with a combined mapping method. The actual rubber distributing, non-linear stress-strain relationship of rubber and bilinear elastic reinforcement are modeled to avoid a departure from the reality. A tread rubber friction model obtained from a Laboratory Abrasion and Skid Tester (LAT 100) is applied to simulate the interaction of the tire with the road. The F&M (force and moment) behaviors of tire cornering subjected to a slip-angle sweep of -8 to 8 degree are studied. To demonstrate the efficiency of the proposed simulation, the computed F&M are compared with results by the implicit solver as well as experimental results from a MTS Flat-Trac Tire Test System. The computed cornering forces agree well with experimental results. Furthermore the footprint shape and contact pressure distribution of several cornering conditions are investigated.
